Vortex 165ZK-35 Aluminum Rear Sprocket 35-Tooth Black Anodized

The Vortex 165ZK-35 is a 35-tooth aluminum rear sprocket finished in a black anodized coating with machined accent highlights — part of Vortex Racing's trusted line of performance drivetrain components manufactured in the USA.

Vortex Racing rear sprockets are engineered for riders who demand precision and performance. Each sprocket is 100% CNC machined from a specially formulated aluminum alloy to tight tolerances, ensuring concentricity and smooth power delivery. The lightweight aluminum construction directly reduces rotating mass, resulting in improved throttle response and more efficient power transfer to the rear wheel.

Key Features:

• 35-Tooth Rear Sprocket — fine-tunes gear ratio for improved acceleration or top-end performance depending on front sprocket pairing
• Lightweight Aluminum Construction — reduces rotating mass compared to OEM steel sprockets for quicker acceleration
• 100% CNC Machined in the USA — precision tolerances ensure concentricity and consistent engagement
• Black Anodized Finish with Machined Accents — corrosion-resistant coating with a distinctive two-tone appearance
• Specially Formulated Alloy — manufactured to Vortex's own material specifications for optimal strength-to-weight ratio
• Optimized Tooth Profile — designed to minimize chain wear and extend drivetrain life

Vortex Racing is a U.S.-based manufacturer with a long history of supplying top-level racing teams across Motocross, Supercross, Road Racing, and Flat Track disciplines. The 165ZK-35 brings that same race-proven engineering to street and track riders seeking a high-quality OEM replacement or performance upgrade sprocket.
